15 Claims.

This invention relates to improvements in cable hangers and more particularly to cable hang ers of the type adapted to be mounted on the side wall of a building and serving to support a cable leading from an exterior electric powerline or the like.

One of the objects of the present invention is to provide a superior cable hanger so constructed and arranged as to be conveniently attached to lo the side of a building or the like and which will support a cable intermediate its ends.

Another object of the present invention is to provide a superior cable hanger of such construction as will firmly support an electric cable and which will securely grip and hold the said cable against slippage relative thereto without damaging the insulation or outer wrapping of the said cable.

Still another object of the present invention is go to provide a superior cable hanger of rugged and simple construction which may be readily and efliciently assembled and installed with a minimum of eflort.

A, further object of the present invention is to provide a superior cable hanger for supporting a cable intermediate its ends and which is formed of simple elements readily manufactured and constructed with a minimum of parts resulting in an article economical for manufacture.

so With the above and other objects in view, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over the prior art and which are not claimed in any separate application.

In the accompanying drawing, in which certain modes of carrying out the present invention are shown for illustratiive purposes:

Fig. 1 is a perspective view of a cable hanger constructed in accordance with the present invention and shown secured to the side wall of a building and supporting an electric cable;

Fig. 2 is an inner end view of the cable hanger detached and showing a portion of a cable which partly broken away;

Fig. 3 is an underside view thereof;

Fig. 4 is a vertical central sectional view taken on the line 4-- l of Fig. 3;

Fig. 5 is a perspective View of the suspension- 50 member;

Fig. 6 is a similar view of the body-member; and

Fig. '7 is a perspective view of the clampingmember.

In the embodiment of the present invention herein chosen for illustration, the cable hanger includes a body-member H! (which also functions as a clamping-member), a suspensionmember H and a clamping-member H2. The body-member i0 is formed of relatively-heavy sheet metal and has an outer end-wall l3 which is bent to form an upper side-wall l4 merging into a bowed or arched inner end-wall Hi. The bowed end-wall it of the bodymember l0 merges downwardly into a lower side-wall [6 which ter- 10 minates adjacent the free end of the outer endwall It of the body-member as is particularly well shown in Figs. 1, 4 and 6.

Along its side-walls I4 and I6 and along its end-wall !5, the body-member H! is provided with a series of transversely-extending corrugations. or cable-gripping ribs H projecting outwardly beyond the outer face of the adjacent marginal portions of the said body-member. The corrugations il just referred to, are spaced from each other in such manner as to provide a continuous band of parallel transversely-extending corrugations upon the respective outer faces of the side-walls I4 and H3 and the end-wall l5 of the body-member 50. The said band of corrugations l'l extends from adjacent the free end of the lower side-wall it of the body-member l0 continuously to a point adjacent the junction of the upper side-wall M and the outer end-wall I3 thereof as shown particularly well in Figs. 4 and 6. The corrugations ll may be readily formed by subjecting the body-member it to a suitable stamping or rolling operation before the said body-member is folded into the shape illustrated in the drawing.

Returning to the suspension-member I I it will be seen by reference to the drawing that the said suspension-member i l is also formed of relatively-heavy sheet metal which is stamped or rolled to form a central-longitudinal cable-positioning and. cable-clamping groove I8. The groove it as thus produced, is flanked on its opposite sides by side-flanges I9l9 respectively forming the respective opposite side-edges of the suspensionanember H. The suspension-member ii is relatively long as compared to its width and is adapted, when. assembled to the bodymember N], to have its inner portion extending inwardly beyond the inner end-wall iii of the said body-member for the purpose hereinafter to appear.

Adjacent its inner end the suspension-member l I is provided with a slot 20 formed on the longitudinal center of the cable-positioning and cableclamping groove ill of the said suspension-mem- 5 her II. For substantially half the distance inwardly from its outer end the groove I8 of the suspension-member II is formed with a series of parallel transversely-extending corrugations or cable-gripping ribs 2I complemental to the corrugations I? of the body-member I0.

By reference to the drawing it will be seen that the relatively-short clamping-member I2 substantially corresponds in cross section to the cross-sectional form of the suspension-member II and is provided with a central-longitudinal cable-positioning and cable-clamping groove 22 which at its outer end is downwardly and outwardly flared as at 23. The clamping-member I2 is formed similar to the suspension-member II with two side-flanges 2424 at its respective opposite edges, each of which is downwardly and outwardly curved at its outer end. The clamping-member I2, thus constructed, has the outer portion of the cable-positioning and cableclamping groove 22 downwardly and outwardly curved to guard against the too-sharp bending of a cable to be supported by the cable hanger in a manner hereinafter to appear. The major portion of the cable-positioning and cable-clamping groove 22 of the clamping-member I2 is formed in a manner similar to the suspension-member I I with transversely-extending corrugations 25.

As shown in Figs. 1 to 4 inclusive, a cable 26 having an insulating covering 2'! is folded around the side-walls I 4 and I6 and around the curved end-wall I5 of the body-member II). The upper reach 26 of the cable 26 may lead from a pole or the like while the lower reach 29 of the said cable may be led to a metering device or the like mounted either exterior of the building or there- To retain the upper reach 28 of the cable 26 in position against the corrugations I! in the upper side-wall IA of the body-member II], the suspension-member II is adapted to be positioned with the outer portion of its cable-positioning and cable-clamping groove I8 placed over the said upper reach 28 of the cable 26. With the clamping-member II placed over the upper reach 28 of the cable 26 as just described, the corrugations 2| thereof will be in engagement with the upper surface of the said cable.

Similarly, the clamping-member I2 is placed with its cable-positioning and cable-clamping groove 22 beneath the lower reach 29 of the cable 26 to retain the said reach in position for engagement with the corrugations I! of the lower side-wall l6 of the body-member I0. With the clamping-member E2 in the position described, the corrugations 25 thereof are in engagement with thecable 26, and the flared portion 23 of the said clamping-member serves to permit the exit of the lower reach 29 of the said cable on a gradualcurve between the lower side-wall I6 of the body-member Ill and the upper face of the clamping-member I2, as shown particularly well in Figs. 2 and 4. By providing for the gradual curving of the cable 26 as described, any sharp bending or kinking of the cable 26 is avoided.

For the purpose of clamping the lower reach 29 of the cable 26 between the lower side-wall I6 of the body-member I0 and the clampingmember I2, as well as for clamping the upper reach 28 of the said cable between the upper sidewall I4 of the said body-member and the suspension-member II, a pair of clamping-bolts 303ll are employed. The said bolts 3fi30 respectively extend downwardly through one of two perforations 3I-3I in the side flanges I9--I9 of the suspension-member II, thence downwardly through perforations 32--32 in the upper sidewall Id of the body-member II]. The said clamping-bolts 30-30 pass downwardly through the hollow interior of the said body-member and extend through perforations 33-33 in the lower side-wall I6 of the said body-member and thence downwardly through perforations 3434 in the side flanges 24-24 of the clamping-member I2. Each of the said clamping-bolts 3030 has threaded onto its threaded lower end a nut 35 which, when seated, bears against the under face of the adjacent one of the side flanges 2424 of the clamping-member I2.

When the cable 26 is installed as shown in the drawing, and the nut 35 of each of the clampingbolts 30-30 is tightened, the said cable will be firmly gripped between the complemental corrugations I! of the body-member I0 and the corrugations 2| and 25 respectively of the suspension-member II and the clamping-member I2. The pressure or clamping action exerted by the clamping-bolts 3036 and their respective nuts 35 will upwardly flex the lower side-wall I6 of the body-member Ill, and in the event that it becomes necessary to apply excessive clamping pressure, the outer end-wall I3 will serve as a stop against which the outer portion of the said lower side-wall I6 may come to rest.

The groove I8 in the suspension-member II and the groove 22 in the clamping-member I2 serve to hold the upper and lower reaches 28 and 29 of the cable 26 against displacement laterally of the body-member II].

By reference to Fig. 1 it will be seen that the cable hanger may be securely mounted on the side wall of a building or the like by hooking the elongated slot 20 formed in the suspension-member II over a hook 36 or other similar device which latter may be secured in any suitable manner to the side-wall 3'! of the building or other support. In this manner the upper reach 28 of the cable 26 is in position to extend to a pole or the like of a power-line while the lower reach 29 of the said cable is also properly positioned to be led downwardly to a meter or other similar device. It will be understood, of course, that other suitable mounting-means other than the hook 36 may be employed for supporting the cable hanger.

By means of the cable hanger herein shown and described, it will be seen that a cable such as the cable 26 may be securely supported and that the said cable is held against relative slipping movement with respect to the said cable hanger. It will also be noted that due to the construction herein shown and described that the cable 26 is folded around a corrugated portion of the cable hanger and is securely clamped in place in such manner as to subject the major portion of the said cable folded around the cable hanger to the anchoring effect of the corrugations respectively formed in the parts I0, II and I2.

It will thus be apparent that the cable hanger serves to securely support a cable and that the same may be coupled to the cable in an efficient manner requiring a minimum of operations. Furthermore, the cable hanger is constructed of a minimum number of parts of relatively-heavy construction and which is economical for manufacture.

The invention may be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
